I was looking into upgrading my MR2 a bit and don't know where to start. I have a BT Apex barrel and a Halo B hopper. I would like to add some realism to my gun, like a magazine, stock, something. What would be a good part or upgrade? Also, to get more performance should I get a new board, feed neck, bolt or anything else? If you currently have a upgraded MR2 if you could post pictures I'd appreciate it.
